I have a web domain with hundreds of A records in it. There are about 10 sites that computers within my AD domain need to access via the site's internal DMZ IP's instead the public IP's. I know I can do this by creating a new DNS zone in AD and adding the A records for those particular sites to point to the DMZ addresses. I tried it and it works, but it breaks the other 290 sites that still need to resolve to the public IP's as there is no records for them in the internal DNS zone. Is there a way that I can configure the new zone to only resolve the 10 A records in question and forward all of the other queries for that domain to the public DNS? I'd really like to not have to maintain all 300 A records in 2 different places if I don't have to.
